Rate Limiting

TSTU (Throughput Unit) Limits

• Anonymous: 200 TSTUs/minute
• Authenticated: 1200 TSTUs/minute

Response Headers

X-RateLimit-Limit: 1200

Handling Rate Limits

import time
import requests

def api_call_with_retry(url, headers, max_retries=3):
    for attempt in range(max_retries):
        response = requests.get(url, headers=headers)
        if response.status_code == 429:
            retry_after = int(response.headers.get('Retry-After', 30))
            time.sleep(retry_after)
            continue
        return response
    raise Exception("Rate limit exceeded after retries")

Multi-Repo Work Item Segregation

When a single Azure DevOps project contains multiple repositories, use Area Paths for primary segregation and hierarchical Iteration Paths for repo-scoped sprint/epic tracking.

Target Structure

Area Paths:                          Iteration Paths:
project\                             project\Iteration\
├── repo-a           (per-repo)      ├── Sprint 1        (shared across repos)
├── repo-b           (per-repo)      ├── Sprint 2        (shared across repos)
└── repo-c           (per-repo)      ├── repo-a\         (repo-scoped container)
                                     │   ├── epic-1-...  (auto-created by sync)
                                     │   └── epic-2-...
                                     └── repo-b\         (repo-scoped container)

Path Format Differences (Critical)

Azure DevOps uses two different path formats for iterations:

Setup Commands for a New Repo

# 1. Create area path (if not exists)
az boards area project create --name "<repo-name>" --path "\<project>"

# 2. Create iteration container
az boards iteration project create --name "<repo-name>" --path "\<project>\Iteration"

# 3. Configure BMAD sync (devops-sync-config.yaml)
# areaPath: "<project>\\<repo-name>"
# iterationRootPath: "<repo-name>"

Moving Iterations (No Native Move)

Azure DevOps CLI has no move command for iterations. To restructure:

1. Verify no work items assigned: az boards query --wiql "... WHERE [System.IterationPath] = '...'"
2. Delete: az boards iteration project delete --path "\project\Iteration\old-path" --yes
3. Recreate under new parent: az boards iteration project create --name "name" --path "\project\Iteration\new-parent"
4. Update state files with new iteration IDs

Common Error: TF401347

TF401347: The iteration path does not exist — caused by using the wrong path format. Check:

• --iteration on work items uses Project\Parent\Child (no "Iteration" segment)
• --path on iteration create uses \Project\Iteration\Parent (with "Iteration" segment)

Best Practices

1. Use Batch Operations

• Use mcp__ado__wit_get_work_items_batch_by_ids instead of multiple single calls
• Max 200 items per batch request

2. Minimize Field Selection

• Only request fields you need: fields=System.Id,System.Title,System.State
• Reduces response size and API load

3. Handle Pagination

• Use $top and $skip for large result sets
• Follow continuation tokens when provided

4. Version Control

• Use test operation in JSON Patch for optimistic concurrency
• Always check rev field before updates

5. Error Recovery

• Implement exponential backoff for rate limits
• Log correlation IDs from response headers
